GAS-MAKING AIPARATUS.

I Application filed- 7- To all whom it may concern:

Be it known that I. ienon P. Lown'a citizen of the United States.residing at San l rancisco. in the county of San Francisco and State of(,alit'orniii. have invented improvements in Gas-Making Apparatus. ofwhich the following is a specification.

This invention relates to an improved apparatus for generating gas fronioil. the object of the invention for this purpose which ical inoperation. and which will avoid the deposit and accumulation ofcarbonaceous material.

In the accompanying drawing, Figure l isa broken side elevation of theapparatus; Fig. 2 is :i broken end view thereof", Fig. 3 is a brokenplan view.

Referring to the drawing. 1 represents a casing, lined with refractorymaterial 2. and divided into two chambers 3 by a transyerse wall 4resting uponnn arch 6. Upon other arches 5 at the bottom oi the chambersand at. the same level with the arch 6, is supported loosely -piledrefractory material 7. With the top of each chamber 3 there areconnected av steam supply pipe 8, a gas outlet pipe 9, and a line 10leading to a stacl: 11

and controlled by a valve 12. said flues being also connected bybranches 13, controlled by valyes lite on air supply pipe 15, forfurnishing an air blast-to either chamber. Into a common combustion andgenerating chamber 16 beneath the archeso and 5 discharge two oil pipes17, one beneath each oi the chambers 3. The

gas outlet pipes 9 lead into washers 18.

The method oi operating the apparatus is as follows. The oil supplypipes 17 being opened, one of the fines 10 is closed atthe top and theother opened. and an air blast. is directed into the former fine. and isforced down through the corresponding chamber 3 to burn the oil injectedinto the combustion chamber, the products 035 combustion passing upthrough the other chamber 3, and highly heating refractory materialtherein, and then passing out by the stack. After a snllicient time,

49 the direction of supply of air is reversed and the prodnets ofcombustion are passed upwards through the first chamber, heating in turnthe reiructory material therein, .The air thus supplied for combustionwas highly heated by the refractory material before comgreat heat. Thisoperation is repeated in both directibns alternately, until the twochambers are hroughtto s sufiiciently high temperature for gas making.

Any adhering carbonaceous material which would otherwise be thrown offas smoke is burned oii thereby ugain cconomizing in fuel. Thepreliminary heating being now effected, the gals making stage oi' theprocess begins. Let it be supposed that, at the end of this preliminaryheating, air was supplied to the chamber il'on the right. The oil supply17 on the left is now shut off, as is also the air supply 13 on theright, and in place thereof steam is introduced on the right and passesdownwards through the chamber 3. it thereby becomes superheated vapor inthe combustion and generating chamber. the two passing up through thehighlyheated piles of refractory material in the chamber 3 on the loft.lorming fixed gas, which escapes through the gas outlet pipe 9 into thewasher 18. After thisstep has been continued for a sullicient time. thesteam and oil pipes on the right are shut off, air is admitted from thepipe 15 through the chamber on the left. burning off any -arbon clingingto the refractory material and the products of combustion puss'upthrough the chamber 3 on the right, thereby highly heating therefractory material in said chamber. When it has been sutlicientlyheated, the air is shut oil and steam is introduced in the place of airby the steam pipe on the left. his steam passing down through therefractory material becomes superheated, mixes with the oil in thegenerating-chamber and the two together pass up through the highlyheated refractory material in the chamber 3 on the right, forming fixedgas, which passes off by the pipe into the washer as before. Thisprocess r definitely.

An apparatus tor making gas, comprising: a casing-11 wall dividing theinterior of the easing into two chambers, an arch on which said wallrests, arches below ouch chamber, loosely plied refractory materialthereon, a steam pipe, a gas outlet pipe. at flue, and menus forsupplying an air blast all communicating directly with the top of eachgenerating chamber, means for supplying oil to the if? terior of thecasing beneath the said arches, and means for independently closing thesteam pipe, the fine and the air blast at the top of either chamber,substantially P In witness 5 hereof I have hereunto set my hand inpresence of tw'h subscribing witnesses.
